If you don't recognize the names and faces then the two people involved here are Sir Patrick Stewart and LeVar Burton. Stewart and Burton both played lead characters on Stark Trek: The Next Generation. Stewart was Captain Jean-Luc Picard and Burton was Lt. Commander Geordi La Forge. If you still don't recognize them by now, well then you are a lost soul. Star Trek guy with a VISOR ring a bell?

In the image above you can see that Burton retweeting a picture of Stewart getting tangled in Christmas lights. It's good to see that the actors still have a friendly rapport and that there characters still mean something to them. Star Trek geeks, rejoice!
